Description

Technical Field

[0001] The utility model relates to the field of power exchange, and in particular to a channel opening and closing device and a power exchange station comprising the same. Background Art

[0002] In the current battery swap station technology, a counterweight is usually used to drive the lifting door at the channel entrance to move. However, there is a significant problem with this method, that is, the counterweight may interfere with the normal operation of the battery swap equipment in the channel entrance. Since the channel entrance is a key area for the movement of the battery swap equipment, the counterweight can easily move to the area where the channel entrance is located during the movement process, which may cause it to collide or interfere with the battery swap equipment, which may cause damage to the battery swap equipment or obstruction of its operation. This interference phenomenon not only affects the normal operation of the battery swap equipment at the channel entrance, but may also pose a potential threat to the efficiency and safety of the battery swap station. Therefore, the above-mentioned problems need to be solved urgently. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects in the prior art and provide a channel opening and closing device and a battery swap station including the same.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A channel opening and closing device, the channel opening and closing device includes a channel opening for battery exchange equipment to enter and exit a charging area and a lifting door capable of opening and closing the channel opening, the channel opening opening and closing device also includes an installation door frame, a stroke amplification mechanism and a counterweight, wherein the installation door frame is arranged to define the channel opening, the lifting door is transmission-connected to the counterweight through the stroke amplification mechanism and both are arranged in the installation door frame, the stroke amplification mechanism is used to amplify a first stroke of the lifting and lowering movement of the counterweight into a second stroke of the lifting and lowering movement of the lifting door, when the lifting door rises and opens the channel opening, the counterweight is located above the channel opening, and the lifting door and the counterweight are staggered along the thickness direction of the installation door frame.

[0006] In the technical solution, a travel amplification mechanism is provided to establish a transmission connection between the counterweight and the lifting door, so that the travel amplification mechanism can be used to amplify the travel, so that the lifting displacement of the counterweight can be smaller than the displacement required for opening and closing the lifting door. By reducing the lifting displacement of the counterweight, the counterweight can be installed in the door frame, and the lowering of the counterweight caused by the lifting door will not affect the normal passage of the passage.

[0007] In addition, providing a counterweight can also reduce or even balance the gravity of the lift door, reduce the driving force required to move the lift door, improve the stability of the lift door's movement, and ensure that the lift door can maintain a stable and vertical state during movement.

[0008] In addition, by staggering the lifting door and the counterweight along the thickness direction of the mounting door frame, the space in the mounting door frame can be fully utilized to achieve a compact structure, so that the space occupied by the entire passage opening and closing device can be further reduced.

[0009] Preferably, the passage opening and closing device further comprises a driving mechanism connected to the lifting door through the stroke amplification mechanism, the driving mechanism being arranged in the installation door frame, and the driving mechanism being used to drive the lifting door to move up and down;

[0010] When the lifting door rises and opens the passage opening, the driving mechanism is located above the lifting door.

[0011] In this technical solution, the driving mechanism and the counterweight are used to drive the movement of the lifting door. The counterweight can partially replace the work of the driving mechanism, thereby reducing the load of the driving mechanism, reducing its driving load, helping to reduce the power consumption of the driving mechanism, extending its service life, reducing the frequency of maintenance and replacement, and achieving energy saving to a certain extent. In addition, arranging the driving mechanism at the upper end of the passage opening helps to maximize the use of space, so that the driving mechanism can be installed more compactly in a limited vertical space.

[0012] Preferably, the counterweight is rectangular in shape, and the thickness of the counterweight is smaller than the thickness of the mounting door frame.

[0013] In the technical solution, this structural form can avoid interference between the counterweight and the movement of the lifting door, help ensure the smooth movement of the lifting door, and avoid the setting of its position affecting the normal opening and closing function of the passage. At the same time, by forming the counterweight in a rectangular shape, the counterweight can be ensured to have sufficient weight to reduce or even balance the gravity of the lifting door under the premise that the thickness of the counterweight is relatively thin.

[0014] Preferably, the counterweight and / or the driving mechanism are arranged on a side of the installation door frame facing the charging area.

[0015] In this technical solution, the drive mechanism and the counterweight are placed on one side of the charging area, that is, inside the battery swap station, which can effectively protect these key components from the influence of the external environment or other potential damage factors, help improve their stability and reliability, reduce maintenance requirements, and to a certain extent improve the aesthetics of the battery swap station.

[0016] Preferably, the stroke amplification mechanism is a pulley group, including a driving wheel arranged on the driving mechanism, a fixed pulley arranged on the mounting door frame in parallel with the driving mechanism, and a movable pulley arranged on the counterweight. One end of the driving chain led out from the movable pulley is connected to the mounting door frame, and the other end passes through the fixed pulley and the driving wheel in sequence and then is connected to the lifting door.

[0017] In this technical solution, the characteristic of the movable pulley that can shorten the distance by half can be used to reduce the distance that the stroke amplification mechanism moves after meeting the lifting range of the lifting door. That is, after the lifting door moves a certain distance, the stroke amplification mechanism only needs to move half the distance to meet the movement requirements of the lifting door, so that the lifting door can meet the needs of opening and closing the passageway for the movement of the battery exchange equipment in a limited vertical space, thereby improving the space utilization efficiency. At the same time, the rotation of the driving wheel set on the driving mechanism is used to drive the driving chain of the stroke amplification mechanism to realize the lifting and lowering of the lifting door, and the structure is simpler and more compact.

[0018] Preferably, a track extending along the moving direction of the lifting door is provided at the crossbeam position at the upper end of the mounting door frame along the height direction of the passage opening, and the track is provided on both sides of the counterweight to provide guidance for the lifting and lowering movement of the counterweight.

[0019] In the present technical solution, the setting of the track helps to provide guidance for the movement of the counterweight, ensuring that it moves along the designed track, helping to maintain the smooth movement of the lifting door and reducing swing and deviation during the movement.

[0020] Preferably, along the height direction of the passage opening, a horizontally extending limit portion is provided at the lower end of the track, and the limit portion is used to contact with the lower surface of the counterweight to limit the moving stroke of the counterweight.

[0021] In the present technical solution, the setting of the limit part can effectively limit the moving range of the counterweight, ensure that its movement on the track is precisely controlled, prevent the counterweight from exceeding the designed safety range when the lifting door moves, and interfere with the normal passage of the battery exchange equipment in the channel entrance, helping to avoid potential damage or safety risks.

[0022] Preferably, slide rails extending along the moving direction of the lifting door for moving the lifting door are provided on both sides of the mounting door frame, and sliders compatible with the slide rails are provided on both sides of the lifting door, the sliders are embedded in the slide rails, and the lifting door moves along the extension direction of the slide rails through the sliders.

[0023] In this technical solution, the design of the slide rail and the slider helps to ensure that the lifting door maintains smooth movement during movement, improves the stability of the operation of the channel opening and closing device, and prevents the lifting door from deviating from or detaching from the installation door frame during movement.

[0024] Preferably, a driving mechanism connected to the lifting door through the stroke amplification mechanism is provided on the installation door frame, and an in-place detection component is provided near the passage opening, and the in-place detection component is electrically connected to the driving mechanism;

[0025] The position of the in-place detection component on the mounting door frame is set to: when the lifting door moves to a preset position, it can contact the detection end of the in-place detection component to stop the driving mechanism from continuing to drive the stroke amplification mechanism to drive the lifting door to move.

[0026] In the present technical solution, the in-position detection component is utilized to accurately detect whether the lifting door has moved to the preset position, and the position of the lifting door is timely sent to the driving mechanism in the form of a signal, so that the driving mechanism performs the next step according to the received signal. This design helps to ensure that the lifting door can accurately stop at the desired position, improve the opening and closing accuracy of the passage opening, thereby preventing the lifting door from moving excessively, ensuring the safety performance of the passage opening and closing device, and avoiding safety hazards caused by the lifting door staying in an incorrect position.

[0027] Preferably, the in-place detection component includes a touch arm for contacting the lifting door, and a sensor connected to the touch arm and electrically connected to the driving mechanism. When the lifting door is about to open the passage opening and rises to a preset position, the lifting door will push the touch arm to move. When the lifting door opens the passage opening, the touch arm reaches its limit position and sends a stop signal to the driving mechanism through the sensor.

[0028] In this technical solution, the position of the lifting door can be accurately detected by monitoring the position of the touch arm through the sensor. And the detection of the in-place detection component is more reliable through the mechanical method of the lifting door contacting the touch arm, and the signal can be sent to the driving mechanism in time. This real-time feedback ensures that the in-place detection component monitors the position of the lifting door in a timely and accurate manner.

[0029] Preferably, the connecting end between the stroke amplification mechanism and the lifting door is arranged at the central axis of the lifting door.

[0030] In the technical solution, placing the connection end of the stroke amplification mechanism on the central axis of the lift door can achieve balanced force transmission, help ensure the stable movement of the lift door during opening and closing, and reduce the uneven force and torque it is subjected to. In addition, it also helps prevent the lift door from deflecting or swinging during movement, thereby improving the reliability of movement.

[0031] A battery swap station, comprising the channel opening and closing device as described in any one of the above items.

[0032] In the present technical solution, the channel opening and closing device using the above-mentioned structural form can effectively control the opening and closing of the channel opening in the battery swap station, provide a flexible operating channel for the battery swap equipment, and realize safe and orderly battery replacement services.

[0033] The positive and progressive effects of the utility model are:

[0034] 1. The passage opening and closing device is provided with a stroke amplification mechanism to establish a transmission connection between the counterweight and the lifting door, so that the lifting displacement of the counterweight can be smaller than the displacement required for opening and closing the lifting door by utilizing the stroke amplification characteristic of the stroke amplification mechanism. By reducing the lifting displacement of the counterweight, the counterweight can be installed in the installation door frame, and the lowering of the counterweight caused by the lifting door rising will not affect the normal passage of the passage.

[0035] 2. The passage opening and closing device can also reduce or even balance the gravity of the lift door by setting a counterweight, thereby reducing the driving force required to move the lift door, improving the stability of the lift door movement, and ensuring that the lift door can maintain a stable and vertical state during movement.

[0036] 3. The passage opening and closing device makes full use of the space in the installation door frame by staggering the lifting door and the counterweight along the thickness direction of the installation door frame, thereby realizing a compact structure arrangement and further reducing the space occupied by the entire passage opening and closing device.

[0037] 4. The battery swap station that adopts the channel opening and closing device can effectively control the opening and closing of the channel in the battery swap station, provide a flexible operation channel for the battery swap equipment, and realize safe and orderly battery replacement services.

[0061] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0062] The utility model provides a battery swap station for providing battery swap services to vehicles entering the battery swap station, wherein the battery swap station includes a battery swap area and a charging area, the area for vehicles to enter is the battery swap area, and battery swap equipment is provided in the battery swap area to disassemble and assemble the batteries loaded on the vehicle. After the disassembly and assembly are completed, the battery swap equipment will enter the charging area through a passageway to charge the batteries removed from the vehicle. In order to separate the charging area from the battery swap area while not affecting the normal operation of the battery swap equipment, a passageway opening and closing device will also be provided at the passageway of the battery swap station.

[0063] like Figure 1-Figure 5 As shown, this embodiment provides a preferred structural setting scheme of the channel opening and closing device 100. Among them, the function of the channel opening and closing device 100 is to close and open the channel of the battery swap station. The switching between the open state and the closed state is as shown in FIG. Figure 1 and Figure 2 shown.

[0064] In order to solve the problem that the counterweight takes up a large space, the passage opening and closing device 100 in this embodiment is specifically provided with a mounting door frame 13, a stroke amplification mechanism 200 and a counterweight 14 in addition to the lifting door 12, wherein the mounting door frame 13 encloses the area where the passage opening 11 is located, and the lifting door 12 is connected to the counterweight 14 by a transmission through the stroke amplification mechanism 200, and the counterweight 14 and the stroke amplification mechanism 200 are both arranged in the mounting door frame 13 to avoid crowding out the external space. Among them, the weight of the counterweight 14 is configured to be able to drive the lifting door 12 to rise, and the stroke amplification mechanism 200 is used to amplify the first stroke of the lifting movement of the counterweight 14 into the second stroke of the lifting movement of the lifting door 12, that is, by setting the stroke amplification mechanism 200, the first stroke of the counterweight 14 with a smaller range of movement can be amplified into the second stroke of the lifting movement of the lifting door 12 with a larger range of movement, so that when the lifting door 12 rises and opens the passage opening 11, the counterweight 14 is located above the passage opening 11. By setting a stroke amplification mechanism 200 to construct a transmission connection between the counterweight 14 and the lifting door 12, the stroke amplification mechanism 200 can be used to amplify the stroke, so that the lifting displacement of the counterweight 14 can be smaller than the displacement required by the lifting door 12 to open and close the passage 11. By reducing the lifting displacement of the counterweight 14, the counterweight 14 can be installed in the installation door frame 13, and the descent of the counterweight 14 caused by the lifting door 12 will not affect the normal passage of the power exchange equipment in the passage 11. Among them, the stroke amplification mechanism 200 can adopt a variety of structures to achieve the purpose of stroke amplification. For example, in this embodiment, the purpose of stroke amplification is achieved by the movable pulley principle. In other embodiments, other amplification principles existing in the prior art such as the lever principle can also be used to achieve the purpose of amplification. Specifically in this embodiment, the amplification ratio generated by the movable pulley principle is 1:2, so the weight of the counterweight 14 should be configured to be twice that of the lifting door 12 to completely balance the weight of the lifting door 12. If a stroke amplification mechanism 200 with other amplification ratios is used in other embodiments, the weight of the counterweight 14 can be adjusted as needed.

[0065] In addition, the counterweight 14 can reduce or even balance the gravity of the lift door 12, reduce the driving force required to move the lift door 12, improve the stability of the movement of the lift door 12, and ensure that the lift door 12 can maintain a stable and vertical state during movement.

[0066] In addition, if Figure 5As shown, the lifting door 12 and the counterweight 14 are staggered along the thickness direction of the mounting door frame 13. Specifically, the lifting door 12 is located on the right side of the mounting door frame 13, and the counterweight 14 is located on the left side of the mounting door frame 13. When the counterweight 14 drives the lifting door 12 to move to the desired position, that is, when both move up and down along the height direction of the passage opening 11, the lifting door 12 and the counterweight 14 do not interfere with each other, and will not affect the normal opening and closing function of the lifting door 12 of the passage opening 11. In addition, by staggering the lifting door 12 and the counterweight 14 along the thickness direction of the mounting door frame 13, the space in the mounting door frame 13 can be fully utilized to achieve a compact structure arrangement, so that the space occupied by the entire passage opening and closing device 100 can be further reduced. In order to achieve the purpose of staggering the counterweight 14 and the lifting door 12 in the thickness direction of the installation door frame 13 and avoid interference between the two during the lifting process, the counterweight 14 in this embodiment is shaped like a thin plate to ensure that it has sufficient weight to balance the lifting door 12 when the thickness is small.

[0067] It should be clearly stated that, in this embodiment, Figure 1 As shown, when the lifting door 12 is in the closed state, it completely covers the passage opening 11, so as to effectively prevent people and foreign objects from invading the charging area of ​​the battery swap station, and improve the isolation effect between the charging area and the outside world, meeting the requirements of dust prevention, heat preservation, etc. Of course, in other embodiments, the lifting door 12 can also half-cover or partially cover the passage opening 11 as needed, and the specific coverage degree can be set as needed according to actual needs.

[0068] like Figure 1-Figure 2 and Figure 4 As shown, the passage opening and closing device 100 also includes a driving mechanism 15 that is connected to the lifting door 12 through the stroke amplification mechanism 200. The driving mechanism 15 is arranged in the installation door frame 13 to drive the lifting door 12 to move up and down. Specifically, the driving wheel of the driving mechanism 15 is engaged with the driving chain led from the stroke amplification mechanism 200, and the lifting door 12 is driven to move up by the driving motor driving the driving wheel to rotate. This solution of directly acting on the counterweight mechanism to achieve driving has a relatively simple structure and high reliability. Of course, in other embodiments, linear driving methods such as electric push rods and cylinders can also be used to achieve the lifting and moving of the lifting door.

[0069] In this embodiment, the driving mechanism 15 and the counterweight 14 are used together to drive the movement of the lifting door 12. The weight of the lifting door 12 is balanced by the counterweight 14, so that the load of the driving mechanism 15 is greatly reduced, thereby reducing its driving load, helping to reduce the power consumption of the driving mechanism 15, extending its service life, reducing the frequency of maintenance and replacement, and also achieving energy-saving effects to a certain extent.

[0070] Furthermore, when the lifting door 12 rises and opens the passage opening 11, the driving mechanism 15 is located above the lifting door 12. Such a design helps to maximize the use of space, so that the driving mechanism 15 can be installed more compactly in a limited vertical space.

[0071] In this embodiment, the counterweight 14 and the drive mechanism 15 are both arranged on the side of the mounting door frame 13 facing the charging area. By placing the drive mechanism 15 and the counterweight 14 on one side of the charging area, i.e., inside the battery swap station, these key components can be effectively protected from the influence of the external environment or other potential damage factors, which helps to improve their stability and reliability, reduce maintenance requirements, and also improve the aesthetics of the battery swap station to a certain extent.

[0072] like Figure 1-Figure 2 and Figure 4 As shown, this embodiment also provides a preferred structural setting scheme of a stroke amplification mechanism 200, which specifically realizes the purpose of stroke amplification through the movable pulley principle. The stroke amplification mechanism 200 includes a driving wheel 21 arranged on the driving mechanism 15, a fixed pulley 22 arranged on the mounting door frame 13 in parallel with the driving mechanism 15, and a movable pulley 23 arranged on the counterweight 14. One end of the driving chain led from the movable pulley 23 is connected to the mounting door frame 13, and the other end passes through the fixed pulley 22 and the driving wheel 21 in sequence and then is connected to the lifting door 12.

[0073] In this embodiment, the movable pulley 23 can shorten the distance by half, and the distance moved by the stroke amplification mechanism 200 can be reduced after the lifting range of the lifting door 12 is met. That is, after the lifting door 12 moves a certain distance, the stroke amplification mechanism 200 only needs to move half the distance to meet the movement requirements of the lifting door 12, so that the lifting door 12 can meet the opening and closing of the passage 11 for the movement of the battery replacement equipment in a limited vertical space, thereby improving the space utilization efficiency. At the same time, the driving wheel 21 set on the driving mechanism 15 is rotated to drive the driving chain of the stroke amplification mechanism 200 to realize the lifting and lowering of the lifting door 12, and the structure is simpler and more compact.

[0074] like Figure 1-Figure 2 and Figure 4 As shown, a track 131 extending along the moving direction of the lifting door 12 is provided at the crossbeam position at the upper end of the door frame 13 in the height direction of the passage opening 11 , and the track 131 is provided on both sides of the counterweight 14 to provide guidance for the lifting and lowering movement of the counterweight 14 .

[0075] In this embodiment, the provision of the track 131 helps to provide guidance for the movement of the counterweight 14, ensuring that it moves along a designed track, helping to maintain smooth movement of the lifting door 12 and reducing swing and deviation during movement.

[0076] Preferably, along the height direction of the passage opening 11 , a horizontally extending limit portion 132 is provided at the lower end of the track 131 , and the limit portion 132 is used to contact with the lower surface of the counterweight 14 to limit the movement stroke of the counterweight 14 .

[0077] In this embodiment, the setting of the limit portion 132 can effectively limit the movement range of the counterweight 14, ensuring that its movement on the track 131 is precisely controlled, preventing the counterweight 14 from exceeding the designed safety range when the lifting door 12 moves, and interfering with the normal passage of the battery exchange equipment in the passage opening 11, thereby helping to avoid potential damage or safety risks.

[0078] like Figure 1-Figure 2 and Figure 4 As shown, slide rails 133 extending along the moving direction of the lifting door 12 for moving the lifting door 12 are provided on both sides of the installation door frame 13, and sliders 121 adapted to the slide rails 133 are provided on both sides of the lifting door 12. The sliders 121 and the slide rails 133 are adapted to each other, and preferably the sliders 121 are embedded in the slide rails 133. The lifting door 12 is moved on the installation door frame 13 by the sliders 121 along the extending direction of the slide rails 133.

[0079] In this embodiment, the design of the slide rail 133 and the slider 121 helps to ensure that the lifting door 12 maintains smooth movement during movement, improves the stability of the operation of the passage opening and closing device 100, and prevents the lifting door 12 from deviating from or detaching from the mounting door frame 13 during movement.

[0080] Preferably, there are multiple sliders 121 , which are arranged in pairs on both sides of the lifting door 12 to balance the force of the movement of the lifting door 12 .

[0081] like Figure 3 As shown, an in-place detection component 300 is provided at a position of the installation door frame 13 near the passage opening 11. The in-place detection component 300 is preferably arranged above the installation door frame 13 to detect whether the lifting door 12 rises to a preset position, and the in-place detection component 300 is electrically connected to the driving mechanism 15.

[0082] Among them, the in-place detection component 300 is arranged at the middle position of the installation door frame 13 and is relatively close to the lifting door 12, so that it can contact the detection end of the in-place detection component 300 when the lifting door 12 moves to a preset position. After the in-place detection component 300 contacts the lifting door 12, a stop driving signal is sent to the driving mechanism 15 through signal transmission to stop the driving mechanism 15 from continuing to drive the stroke amplification mechanism 200 to drive the lifting door 12 to move.

[0083] In this embodiment, by utilizing the in-position detection component 300, it is possible to accurately detect whether the lifting door 12 has moved to the preset position, and timely send the position of the lifting door 12 to the driving mechanism 15 in the form of a signal, so that the driving mechanism 15 can perform the next step according to the received signal. This design helps to ensure that the lifting door 12 can accurately stop at the desired position, improve the opening and closing accuracy of the passage opening 11, thereby preventing the lifting door 12 from moving excessively, ensuring the safety performance of the passage opening and closing device 100, and avoiding the safety hazards caused by the lifting door 12 staying in an incorrect position.

[0084] Specifically, there are two in-place detection components 300, which are respectively arranged on the left and right sides of the installation door frame 13, and both are located above the lifting door 12, so as to perform double detection on the movement of the lifting door 12. When the in-place detection component 300 on one side fails, the position detection can also be performed through the in-place detection component 300 on the other side. The advantage of setting two is that the accuracy of the position detection of the lifting door 12 is improved.

[0085] like Figure 3 As shown, the in-position detection component 300 includes a touch arm 31 and a sensor 32. The touch arm 31 is used to contact the lifting door 12, and the sensor 32 is connected to the touch arm 31 and electrically connected to the driving mechanism 15. When the lifting door 12 is about to open the passage opening 11 and rises to a preset position, the lifting door 12 will push the touch arm 31 to move. When the lifting door 12 opens the passage opening 11, the touch arm 31 reaches its limit position and sends a stop signal to the driving mechanism 15 through the sensor 32.

[0086] In this embodiment, the position of the lifting door 12 can be accurately detected by monitoring the position of the touch arm 31 through the sensor 32. And the detection of the position of the lifting door 12 by the mechanical method of the lifting door 12 contacting the touch arm 31 makes the detection of the in-place detection component 300 more reliable, and can send a signal to the driving mechanism 15 in time. This real-time feedback ensures that the monitoring of the position of the lifting door 12 by the in-place detection component 300 is timely and accurate.

[0087] like Figure 1-Figure 2 and Figure 4 As shown, the connection end of the stroke amplification mechanism 200 and the lifting door 12 is arranged at the central axis of the lifting door 12. Such an arrangement can achieve balanced force transmission, help ensure the stable movement of the lifting door 12 during the opening and closing process, and reduce the uneven force and torque it is subjected to. In addition, it also helps to prevent the lifting door 12 from deflecting or swinging during the movement process, thereby improving the reliability of movement.

[0088] The sensor 32 can be selected in its form as needed, such as a contact sensor 32 or a non-contact sensor 32, without any specific limitation.

[0089] The channel opening and closing device 100 in this embodiment is used in a battery swap station to realize the opening and closing of the channel opening of the battery swap station. However, in other embodiments, the channel opening and closing device 100 can also be used in other equipment in the field of battery swapping to also realize the purpose of reliably opening and closing the channel opening.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
